Madison Keys stunned Iga Swiatek to set up an Australian Open final against two-time defending champion Aryna Sabalenka.

Madison Keys has charged into the Australian Open final and will meet two-time defending champion Aryna Sabalenka in Saturday’s championship (3 a.m. ET, ESPN).

The Belarusian has been unbeatable in Melbourne for years, but she's running into in absolute buzzsaw.

But there's one person that Keys hopes she won't be hearing from before she steps into Rod Laver Arena to face Aryna Sabalenka for the women's singles title on Saturday night in Melbourne: her good friend and fellow American Frances Tiafoe.

American Madison Keys will seek her first Grand Slam title after upsetting No. 2 seed Iga Swiatek in the Australian Open semifinals.

Veteran Madison Keys took down No. 2 seed Iga Swiatek in a thrilling three-set match (5-7, 6-1, 7-6(8)) in the Australian Open semifinal on Thursday to advance to just the second Grand Slam final of her career.

Keys saved a match point before winning in a final set tie-break while Sabalenka saw off close friend Paula Badosa.

American Madison Keys beat No. 2 seeded Iga Swiatek in a thrilling 5-7, 6-1, 7-6(8) victory in the semifinals, defeating Swiatek in two hours and 38 minutes to advance to her first Australian Open final.

The Madison Keys who will play the two-time defending champion for the title at the Australian Open is not the same Madison Keys who was the runner-up at the 2017 U.S. Open, the one other time the Rock Island native participated in a Grand Slam final.

Madison Keys was hitting swinging volleys at the Quad City Tennis Club long before her coaches were even teaching it.

The Polish player was sensationally overtaken by the 29-year-old American, who won the third-set supertiebreak with a score of 5-7 6-1 7-6 (8), reaching the second Slam final of her career eight years after the one at the 2017 US Open, lost to Sloane Stephens.
